This script accepts a number or string and formats it like U.S. currency. Adds the dollar sign, rounds to two places past the decimal, adds place holding zeros, and commas where appropriate.  Occurs when the user clicks the button or when they finish entering the money amount (and click into the next field).

&lt;!-- TWO STEPS TO INSTALL CURRENCY FORMAT:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;
